An urban transformation and construction method is disclosed that creates a tropical style swimming lagoon at vacant and/or abandoned sites. The transformation includes demolishing at least part of the vacant or abandoned site, excavating material from within the site; forming a basin for a large water body having a surface area of at least 3,000 m2, and constructing water containment walls on a first section of the basin to form a waterfront perimeter. The shape of the waterfront perimeter is mainly curved, the basin has a maximum width of 300 meters, and the bottom is covered with a non-permeable material. A sloped access area is constructed in a second section of the basin to form a beach. A barrier is constructed to control access into the area including the beach. At least one recreational facility is constructed including restaurants, bars, kiosks, stores, and/or cafes about the waterfront perimeter.

A system and a method is provided for automatically changing color of pool lights to provide a visual notification regarding any change or anomaly associated with pool water. The system may comprise a receiver adapted to receive a measured value corresponding to one or more water quality parameters associated with water of a pool. The system may comprise a controller to analyze the measured value corresponding to the one or more water quality parameter to determine whether there is an anomaly associated with one or more of the water quality parameters; and a transmitter adapted to transmit a signal to one or more lights of the pool for changing from a first state to a second state based on the anomaly.

A pool cleaner generator module with magnetic coupling. The generator module can include a housing, a paddle wheel, a magnetic follower, and a generator. The generator can power components of the pool cleaner, such as light emitting diode (LEDs). The housing can be removably coupled to the pool cleaner and can include a flow directing portion positioned in a fluid path of the pool cleaner. The paddle wheel can be located adjacent to the flow directing portion and can rotate in response to fluid flow through the fluid path. The generator can be magnetically coupled to the paddle wheel and can generate power through rotation of the paddle wheel. The LED can be coupled to the generator and can receive the generated power from the generator to illuminate an area adjacent to the pool cleaner.

A pool or spa control system includes a sensor system with one or more sensors in contact with a main body of water. The sensor system measures water condition data of the body of water and is mounted on a wall submerged in the main body of water. The pool or spa control system also includes a modem that facilitates data communications between the sensor system and communication equipment positioned at a different location from the main body of water.

The disclosure provides an outdoor device for simulating a pond ecosystem comprising a plurality of simulated ponds connected together by pipelines and including an adjusting pool, a plurality of control groups and a plurality of treatment groups with different concentrations; the plurality of control groups and the treatment groups are randomly distributed in the ponds according to a random draw method or a random allocation method, and the adjusting pool is a transfer station for water inlets and outlets of the ponds. According to the device, the plurality of control groups and treatment groups are arranged in a system, achieving a scale of a middle-scale pond ecological simulation system, which can stimulate an actual complex hydrostatic ecological system including a plurality of aquatic macrophytes, algae, zooplankton, benthos and microorganisms, and evaluate the effects of the complex ecological efficiency caused by chemical pollutants entering an actual water body.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

Disclosed is an ultraviolet light disinfection apparatus mounted on a water pipe that is connected to a massage pool. The ultraviolet light disinfection apparatus comprises: a housing mounted on the water pipe and in closed connection with the water pipe; a PCB disposed inside the housing and provided with a UVC-LED light source and a wire, the wire protruding from the housing to connect to the power source; an ultraviolet light-transmitting body disposed on the housing, such that ultraviolet light at UVC wavelength range produced by the UVC-LED light source can enter into water body inside the water pipe through the ultraviolet-transmitting body. The present invention can disinfect the water body inside the water pipe. Also provided are a control box and a massage pool.

An adapter assembly for securing a luminaire to a niche formed in a wall of a pool or spa. The assembly comprises a mounting bracket having a rear portion shaped and sized to fit within the niche and a front portion comprising a peripheral flange sized to engage the wall surrounding the niche. The mounting bracket enables the luminaire to be secured thereto and be visible from a front side thereof. The assembly includes at least one clamping device attached to the rear portion of the mounting bracket and configured to secure the mounting bracket to the niche. In a preferred embodiment, the clamping device comprises a clamping arm and drive member. The clamping arm is pivotally connected to the mounting bracket such that the mounting bracket is drawn into the niche and the peripheral flange of the mounting bracket is drawn towards the wall surrounding the niche.

Aspects of the disclosed technology include a lighted inflatable pool including: a wall including a first inflatable chamber; a base; at least one lighting element disposed within the wall, the at least one lighting element being configured to emit light; and a receiver connected to the at least one lighting element, the receiver being configured to receive a command for controlling the lighting element and to control the at least one lighting element in correspondence with the command.

A system and method for projecting a still shot or video projection into a body of water is described herein.
